MicroRNA-27a Promotes Proliferation, Migration and Invasion by Targeting<b><i>MAP2K4</i></b>in Human Osteosarcoma Cells

Abstract

This is the first study showing that miR-27a can function as an oncogene by targeting MAP2K4 in the osteosarcoma MG63 cell line. Inhibition of miR-27a increases MAP2K4 expression, which in turn inhibits cell proliferation and migration through the JNK/p38 signaling pathway in MG63 cells. These findings may help us understand the molecular mechanism of miR-27a in the tumorigenesis of osteosarcoma and may provide new diagnostic and therapeutic options for the treatment of this neoplasia.
